How many chromosomes does a typical somatic cell have? 2. How many chromosomes are in that cell after anaphase of mitosis? 3. How many chromosomes are in each daughter cell produced by mitosis? 4. How many chromosomes are in a cell in G2 phase? Compare and Contrast: Complete the following Venn Diagram, comparing and contrasting Mitosis and Binary Fission. Identify at least 2 similarities and 2 differences: Explanation: Be able to answer the following questions using details, cause/effect relationships, and unit vocabulary: 1. What is cancer? 2. What must happen to cells to cause them to become cancerous (include the phase of the cell cycle in which non-cancerous cells may become cancerous): 3. What is the purpose of mitosis? Why can’t eukaryotic cells just split down the middle like bacteria do?
